This paper will address dosimetry and monitoring techniques for total ionizing dose (TID) testing of electronics devices. We first discuss the basic principles dosimetry, as well most common dosimetric quantities units, used determination energy deposited in a given medium by radiation. In Section III, we give an overview available radiation, along with mechanisms exploited their operation. IV, issues factors affecting measurements, some practical “hints” about selection use presented...
The high-luminosity LHC (HL-LHC) upgrade is setting now a new challenge for particle detector technologies. increase in luminosity will produce background the gas-based muon detectors that ten times higher than under conditions at LHC. detailed knowledge of performance presence such high crucial an optimized design and efficient operation after HL-LHC upgrade.
